AFAIK my code did not replace it.  Both codes are still with us.

This keep coming up and the answer is still the same: no, I won't work on
it, because I'm deeply convinced it cannot be done without introducing
worse problems.  Such consistency is actually pretty low in the list
of priorities.  Much more important is e.g. to ensure that repeated movement
commands do not get stuck.

I have neither time nor inclination to get into more details again.
Check past discussions about it,
